Mr. Lydekker exhibited the skull of an English Fox (Oanis 

 wipes) with two perfect canine teeth on each side of the upper 

 jaw (see text-fig. 1). A dog's skull with the upper canine of each

 the full duplication of the corresponding teeth of both sides was 

 afforded by the skull of a Cat figured on p. 225 of the work cited. 

 The Fox to which the skull belonged had been killed by the 

 South Oxfordshire Hounds. The skull itself was the property of 

 Mr. H, G. Pease.

 origin of the Tanganyikan fauna ; the smaller lake had proved to 

 be very thinly populated with Fishes, which all belonged to widely

 Tanganyika elements, with two that might prove to be endemic. 

 The list of the Fishes from the two lakes comprised 91 species,

 described consisted of examples of 50 species, 26 of which were
